...o a cell. Since leptin is the body’s messenger boy to the brain for “stop eating, we’re full?messages, and JAK2 helps receive those messages as they arrive, SH2B1’s partnership with JAK2 is an important one. In a previous paper, Rui and his former mentor and current colleague Christin Carter-Su, Ph.D...

...toxoplasmosis on the probability of the birth of a boy in humans. Latent toxoplasmosis is asymptomatic but is usually a life-long infection characterised by the presence of anti-Toxoplasma antibodies in the blood.

Leading reason for corneal transplants comes into focus

...that, a large Indiana family with FCD, including a boy of 10, led the team to yet another gene variant, on chromosome 13. The scientists use linkage analysis, a process-of-elimination gene-hunting technique that analyzes inheritance patterns in families with relatively large numbers of affected indivi...

Fighting like a girl or boy determined by gene in fruit flies

Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the Nov. 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene...

Inheriting a tendency to brain infection

... In 2005, Casanova later identified a 15-year-old boy who developed brain damage due to herpes simplex infection. Casanova found that the boy's blood cells failed to produce an important immune signalling molecule, type I interferon, when challenged with the virus in a laboratory flask. At about the s...

...the novel Lazarillo de Tormes, in which the orphan boy Làzaro helps a blind man see. Of the molecules known to control TRP channels, a key player is diacylglycerol, known as DAG. DAG is known to be made by a well-studied biochemical pathway. The researchers found that Lazaro provides a second way to mak...

Minor mutations in avian flu virus increase chances of human infection

... originally isolated from a 10-year-old Vietnamese boy who died from the infection in 2004. The hemagglutinin (HA) structure from the Viet04 virus was found to be closely related to the 1918 virus HA, which caused some 50 million deaths worldwide. Using a recently developed microarray technology-hundre...

Engineers discover why toucan beaks are models of lightweight strength

As a boy growing up in Brazil 40 years ago, Marc A. Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now a materials scientist and professor of mechanical and aerospace engineering at UCSD's Jacobs S...
